Sepeipi sa Tšireletso sa RSiC
Tlhahisoleseding ea Sehlahisoa
Liphaephe tsa Tšireletso ea Carbide ea Siliconke dikarolo tse ikgethang tsa tubula tse entsweng ka thepa ya ceramic ya silicon carbide (SiC), tse sebediswang haholoholo ho sireletsa dikarolo tse bonolo (tse kang di-thermocouple) kapa e le dikarolo tsa mantlha disebedisweng tsa ho tsamaisa mokelikeli o mocheso o phahameng le phapanyetsano ya mocheso.
Lihlahisoa tsa rona li etsoa haholo-holo ka ho sebelisa mekhoa e meraro:Ho sintering ha karabelo (RBSiC), Recrystallization (RSiC), Silicon nitride e tlamiloeng ka silicon carbide (NSiC)
1. Liphaephe tsa tšireletso tsa RSiC
Ka ho sebedisa phofo e nyane ya SiC e hlwekileng haholo e le thepa e tala, e silwa mochesong o phahameng (2000–2200℃). Sebopeho se teteaneng se thehwa ka ho kopanngwa ha di-crystallization le moedi wa dithollo wa dikarolwana tsa SiC ka botsona, ntle le mohato o eketsehileng wa ho kopanya.
Litšobotsi tsa Bohlokoa:
Khanyetso e Ikhethang ea Mocheso o Phahameng:Mocheso oa ts'ebetso oa nako e telele ho fihlela ho 1600℃, khanyetso ea nako e khuts'oane ho 1800℃, e leng se etsang hore e be e ntle ka ho fetisisa mabapi le khanyetso ea mocheso o phahameng har'a mefuta e meraro, e loketseng li-oven tsa mocheso o phahameng haholo (joalo ka li-oven tsa sintering tsa ceramic le li-oven tsa metallurgical blast).
Khanyetso e Hlollang ea Oxidation:Maemong a mocheso o phahameng, filimi e teteaneng e sireletsang SiO₂ e thehoa holim'a metsi, e thibela ho oxidation ho eketsehileng ha SiC ea ka hare, e bonts'a botsitso bo phahameng haholo sepakapakeng se oxidating.
Katoloso ea Thermal e Tlase Haholo:Koefficient ea katoloso ea mocheso ke 4.5 × 10⁻⁶ /℃ feela, e fanang ka khanyetso e ntle ea ho thothomela ha mocheso, leha e le tlase hanyane ho feta ea carbide ea silicon e kopantsoeng le nitride.
Ho thatafala ho hoholo le ho hanyetsa ho tsofala ho hoholo:Ka boima ba Mohs bo haufi le 9, e bonahatsa khanyetso e ikhethang khahlanong le khoholeho ea thepa le ho hohlana, e leng se etsang hore e lokele maemo a moea o phallang mochesong o phahameng le a phallo ea metsi a nang le likaroloana tse tiileng.
Ho tsitsa ha lik'hemik'hale ho matla:E hanela li-acid tse matla le li-alkali, 'me ha e arabele le boholo ba litšepe tse qhibilihisitsoeng.
Meeli:
Mocheso o phahameng haholo oa ho chesa, o fellang ka masoba a manyane a phahameng (hoo e ka bang 5%–8%) le khanyetso e phahameng e fokolang hanyane; ho tetebela ha mocheso oa kamore ho phahameng haholo, le khanyetso ea tšusumetso ha li ntle joalo ka silicon carbide e kopantsoeng le silicon nitride.
2. Liphaephe tsa tšireletso ea RBSiC
Ka ho sebedisa dikarolwana tsa SiC le graphite e le thepa e tala, thepa e feta tshebetsong ya ho kenella ha silicon. Silicon e metsi e kenella le ho tlatsa masoba, e arabela le graphite ho theha mohato o motjha wa SiC, qetellong e bopa sebopeho se kopaneng sa "SiC framework + free silicon".
Litšobotsi tsa Bohlokoa:
Sekhahla se phahameng le masoba a tlase:Silicone e sa lefelloeng e tlatsa masoba, e fokotsa masoba ho fihlela ka tlase ho 1%, e leng se fellang ka ho se kene hantle ha moea le ho hanyetsa khatello e phahameng, e loketseng khatello e phahameng le mocheso o phahameng.
maemo a ho kwala (jwalo ka dionto tse futhumatsang kgatello).
Litšobotsi tse ntle tsa mechini:Matla a ho kokomoha ha mocheso wa kamore ke 250–400MPa, ho tiea ha ho robeha ho hoholo, le ho hanyetsa ho matla ho feta silicon carbide e ntjhafaditsweng.
Khanyetso e itekanetseng ea mocheso o phahameng:Mocheso oa ts'ebetso oa nako e telele ke 1200℃. Ka holimo ho 1350℃, silicon e lokolohileng ea nolofala, e leng se lebisang ho fokotseheng ha matla le ho fokotsa ts'ebetso ea mocheso o phahameng.
Ho sebetsa hantle:Boteng ba silicon e lokolohileng bo fokotsa ho robeha ha thepa, e leng se etsang hore ho be bonolo ho e kenya ka dibopeho tse rarahaneng, e leng se fellang ka ditjeo tse tlase tsa tlhahiso.
Meeli:
Tshebetso ya mocheso o phahameng e lekanyetswa ke silicon e lokolohileng, e leng se etsang hore e se ke ya lokela ho sebediswa nako e telele ho feta 1350℃; silicon e lokolohileng e arabela habonolo le di-alkali tse matla, aluminium e qhibilihisitsweng, jj., e leng se fellang ka sebaka se sesesaane sa ho hanyetsa mafome.
3. Phaephe ea tšireletso ea NSiSC
Ke thepa e kopaneng e entsoeng ka ho hokahanya likaroloana tsa SiC ka thata ka har'a matrix ea silicon carbide ka ho hlahisa Si₃N₄ e le mohato o tlamang ka karabelo ea nitriding.
Likarolo tsa Bohlokoa:
1. Khanyetso ea ho Tšoha ha Thermal e Phahameng ka ho Fetisisa:Koefficient e tlase ea katoloso ea mocheso le ho tiea ho hoholo ha karolo e kopantsoeng ea Si₃N₄ ho lumella tube e sireletsang ho mamella ho futhumala le ho pholisa ka potlako ho feta 1000℃ ntle le ho petsoha ka lebaka la liphetoho tsa tšohanyetso tsa mocheso, e leng se etsang hore e lokele maemo a ts'ebetso a nang le ho feto-fetoha ha mocheso khafetsa.
2. Khanyetso e Hlollang ea Ts'enyeho:E tsitsitse haholo khahlanong le li-acid tse matla, li-alkali tse matla, litšepe tse qhibilihisitsoeng (tse kang aluminium le koporo), le matsoai a qhibilihisitsoeng, e leng se etsang hore e tšoanelehe haholo bakeng sa libaka tse senyang liindastering tsa lik'hemik'hale le tsa tšepe.
3. Matla a Phahameng a Mechini:Matla a ho kokobela mochesong wa kamore a fihla ho 300–500 MPa, ka ho boloka matla a betere mochesong o phahameng ho feta dihlahiswa tse hlwekileng tsa SiC, le ho hanyetsa ho matla ha tshusumetso.
4. Mocheso o sebetsang:Mocheso oa ts'ebetso oa nako e telele ke 1350℃, bokhoni ba ho mamella nako e khuts'oane ho fihlela ho 1500℃.
5. Ho Sireletsa ho Molemo:E boloka mocheso o motle oa motlakase esita le mochesong o phahameng, e thibela tšitiso ea lets'oao la thermocouple.
Meeli:
Khanyetso ea oxidation e batla e le tlase ho feta silicon carbide e nchafalitsoeng; tšebeliso ea nako e telele sepakapakeng se matla sa oxidation e ka lebisa ho peeling ha lera la oxide ea holim'a metsi.
